Jasmone is a natural organic compound extracted from the volatile portion of the oil from jasmine flowers. The natural extract contains only the cis form, while the synthetic material is often a mixture containing both forms, with the cis form predominating. Commercially it is used primarily in perfumes and cosmetics. Some studies on rodents had shown that cis-jasmine had a tranquillizing effect on the brain, possibly through the GABA-A receptors response.

P-nitrobiphenyl (PNB) is used as an intermediate for 4-aminobiphenyl. It was shown that PNB was a urinary bladder carcinogen in dogs. Reports of carcinogenicity in human do not exist, but 4-aminobiphenyl is a carcinogen for human, that is why the assumption exists that exposed in men to 4-aminobiphenyl may have been partially due to PNB. In addition, information exists that PNB has been studied in trials for the treatment of pelvic organ prolapse.

Cupric nitrate (Copper(II) nitrate) is an inorganic compound that forms a blue crystalline solid. Copper(II) nitrate finds a variety of applications, the main one being its conversion to copper(II) oxide, which is used as catalyst for a variety of processes in organic chemistry. Its solutions are used in textiles and polishing agents for other metals. Copper nitrates are found in some pyrotechnics. It is often used in school laboratories to demonstrate chemical voltaic cell reactions. Strong oxidizing agent.
